PROTECTIVE FEATURES
Overcurrent/overcapacity,
solar panel
If the charging current or charging power from the solar panel exceeds
the rated data of the charge controller the current and power are
automatically limited to the rated data.
NOTE: When connecting solar panels in series make sure that the
open circuit voltage for the solar panel group cannot exceed the
highest stipulated open circuit voltage for the charge regulator.
Otherwise the charge controller can be damaged.
Short circuit, solar panel
The charge controller is short-circuit protected – when it is not in
charging mode it will not be damaged if the solar panel/group is short
circuited.
Reverse polarisation,
solar panel
If the solar panel is connected with the wrong polarity the charge
controller will not be damaged. Normal functionality is restored when
the reverse polarisation is corrected.
NOTE: The reverse polarisation
protection cannot handle solar panels with power exceeding
1.5 times the rated power of the charge controller. If such solar
panels are connected with the wrong polarity the charge
controller will be damaged.
Night discharge
protection (reverse
current protection) Prevents the battery discharging during the night as a result of reverse
current through the solar panel.
Reverse polarisation,
battery
Complete protection from reverse polarisation of the battery – no
damage caused by any reverse polarisation. Normal functionality
is restored when the reverse polarisation is corrected.
NOTE: This
protection only works for lithium batteries. With correct connection
on the solar panel side and reverse polarised connection of other
types of batteries the charge controller will be damaged.
Overvoltage, battery
If the battery voltage reaches the disconnect limit for battery
overvoltage, the battery charging will be interrupted automatically to
protect the battery from overcharging.
Overdischarging, battery
If the battery voltage reaches the disconnect limit for battery
undervoltage, the consumers will be disconnected automatically
to protect the battery from overdischarging.
NOTE: All consumers
connected to the charge controller are disconnected. Consumers
connected directly to the battery remain connected and can
continue to discharge the battery.
Overheating, battery
The charge controller automatically interrupts charging/discharging if
the battery temperature detected by the temperature sensor (option)
is lower than the low temperature protection threshold (LTPT).
When the battery temperature rises over LTPT the charging/
discharging resumes automatically. LTPT is as standard set to 0°C,
but can be set in the interval of 10 to 40°C.
